REMOVABLE CAN FOR ICE-MAKING MACHINES.

To all whom it ma concern.

Be it known t at I, CHAnLns SOUTHARD RALPH, a citizen of the Umted States, residing at Sacramento, in the county of Sacramento and State of California, have 1nvented a new and useful Improvement 1n Removable Cans for Ice-Making Machines, of which the following is a specification.

This invention relates to an improvement in removable cans for ice making machines,-

together with means for placing the can in position and for using the can during the freezing operation, the improvement consisting in the construction of a bottom portion of the can and certain attachments applied thereto.

The object of the invention 1s to enable the drawing of core water which usually contains any impurities that may be held in solution in the water, through the bottom of the can by means of a pipe having communication with a suitable drain or sewer, also to fill the can with water to be frozen through the same pipe, and also to inject air into the can during the freezing operation, through the same pipe, thereby agitating the water and shortenlng the t1me of freezing. I

These objects are attained by the ObJGCtS hereinafter described, pointed out in the claim and shown in the accompanying drawings, in which,

Figure 1 is a sectional side elevation of one of the cans, the bottom of the freezing tank being also shown in section. Fig. 2 is a section on the line 22 of Fig. 1.

In these drawings, 1 represents a metal ice can of the usual size and shape, and the sides of said can fit within a flanged bottom 2, said bottom being provided with an upwardly extending flange 3 adapted to overlap the sides of the can and be riveted or soldered thereto, and the said bottom is also provided with a somewhat deeper depending flange 4L and with an outwardly extending flange 5, the latter flange being preferably just above the plane of the bottom 2. These cans are designed to be placed within the usual brine tank containing the freezing solution and the bottom 6 of said tank is suitably cut out to receive the flanges 4:, a rubber gasket 7 fitting in said out Specification of Letters Patent.

out portion and lying between the flange 5 and the upper face of the tank bottom 6. An angled rame or bracket 8 surrounds the opening in the tank bottom, and said frame is provided with suitable openings adapted to register with openings in the flange 4, and wedge-shaped locking pins 9 pass through the alining openings and hold the can in place. A suitable pipe 10 is secured centrally to the bottom 2 of the can being secured by a union or coupling so as to be readily detachable. A T 11 carried by the pipe 10 is connected to an air pipe 12 and a water pipe 13 is connected to the pipe 10 by a suitable elbow 14. The pipe 13 is adapted to convey water to a suitable drain or sewer not shown, and also to receive water from a suitable pump, not shown.

In operation the can is placed in position upon the bottom of the solution tank as shown in Fig. 1, the pipe is connected, and filtered water is then allowed to fill the can through the pipe 13 until within four inches of the top of the can. The water supply is then cut off, air is forced through the pipe 12 and gently agitates the water while freezing. The air supply is then cut off and the center or core water is then drawn off through the pipe 13 which is now placed in communication with any suitable form of drain or water discharge. When said core water has been withdrawn fresh filtered water is then again pumped through the pipe 13 and takes the place of the removed core water, and the freezing process is then continued. When this process has been completed the keys 9 are removed and the pipe 10 disconnected and the can can be lifted from position and carried to the platform upon which the ice is to .be dumped, the brine being first dumped ofl.

What I claim is The combination with a freezing tank having a bottom provided with a can receiving opening, a can having a bottom provided with an outwardly extending flange adapted to rest upon the marginal portions of said opening and having a depending flange adapted to pass through said opening, a packing material fitting in said open- Q 1,129,,e1e
